Dimetrodon grandis is a species of sail-backed synapsid, originally formally described in 1907. D. grandis inhabited lived early Permain period, between 295 and 272 million years ago. Fossilized remains of this synapsid have been discovered in the American southwest, notably present-day Oklahoma and Texas. The genus name Dimetrodon means “two measures of teeth,” and the defining feature of the genus is the prominent neural sail along its back, which is formed by elongated spines extended from the vertebrate.
Dimetrodon was one of the prehistoric species documented as having been cloned by the Department of Prehistoric Wildlife since the 2018 Lockwood Manor incident. The animal’s measurements were observed to be 226kg in weight, and it was 1.8m tall, and 4.5m long. The animal was considered to be a carnivore, mostly eating amphibians and fish. Early reports from the DPW indicate that this species preferred underground spaces.
